I’m unaware of the impact.
But, let’s be fair. The kemper release is a major release adding brand new reverbs that we’re not contemplated when those patches were released. In fact, some of them were profiles released when they were “hacking” things together to try to achieve the tones you now can by default.
Line 6 would break stuff just because they were unbreaking something somewhere else. Minor releases would render whole workflows useless and it would be unrelated to net new functionality.
